I somewhat recently connected Emporia Vue's 'net production/consumption' metric to my OpenEVSE so I can make use of the 'eco divert' feature that only charges from excess solar production. Since my utility charges for transmission of net-metered power, this leads to some savings. When we have cooler summer weather it shows up very nicely on the graph.

EVSE view: OpenEVSE eco divert

(Hopefully this is OK for this community. Not news, but could be a nice highlight/discussion. If not, glad to find another spot to share it.)

Cross-posted! (I kinda wish cross-posts shared comment threads.)

I used vuegraf to publish MQTT from my Emporia Vue, which OpenEVSE can natively consume. I'm running Mosquitto for my MQTT broker.

I've considered flashing my Vue with ESPHome, which people say would make this even easier, but haven't yet.

What other details would be useful?
